iureovsusnr IN PLASTER 'AND srrn-sowrn.

TO ALL WHOM IT MAY CONCERN: i

Be it knewn'that we, DAVID Diet. and O. W. PRESTON, 31a, of Corning, in the. State of I New York, have invented certain new and useful Improvements in Plaster and Seed-Sewers; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, as forming a part of this specificatiom in which Figure 1 is a. side elevation, V i

Figure 2 a rearview, and

Figure 3 a view of the levers for throwing the machine in and out of gear.

To enable others skilled in the art to make and'use our invention, we will now describe its construction and a operation. I

A represents the plaster and seed-box, which we make V-shapcd on the inner side. b is a sliding bar run--' ning longitudinally through box A. Said box is provided with pins e e, the object of which will be fully shown hereafter. This bar is also provided with stirrersa z z, for the purpose of agitating the grain and fertilizingmaterial, thereby causing an uninterrupted flow of both. B are the driving-wheels on shaft or axle G. i The inner side or circumference of these wheels is cairn-shaped, as seen in figrC, and theybeing End to the axle and revolving with it, a reciprocating motion is imparted to the-sliding bar b by the cams working against the pins 0 e. The rear sideof box A is provided with apertures at its bottom to admit of the eirit of the grain,

&c D represents a slide, at the centre of which is the small rack g. d is a shaft, upon which is the pinion an t This pinion works in .rack g, and by means of which the slide 1) is opened or closed, It is a lever securely attached to shaft d. k represents a gutter or'trough, into which the grnin and fertilizing-material fall as they come from box A. m is a revolving shaft, which is provided with a double row of brushes put 'on or through said shaft in spiral form, as indicated infig. 2. The object of these brushes is tosweep and scatter the grain &c., as it falls into thegutter k. ,n represents a pinion on the end of shaft m; G is a gear-wheel on axle C. By means of this wheel motionis communicated to shaft m in a manner hereinafter shown. 0 represents a short lever, one end of which is provided with a sleeve, in which the end of shaft "m revolves. e is also-a lever, slotted as shown in figsQl and 3. This lever is securely fastened at the end of shaft d. w-represents a connectingpiece, the lower end of which is pivoted to lever a, while the upper end is provided with a slot-pin, which works in the slot in lever s This pin has athumb-screw attached to it for securing the connecting-piece a: in the slot. y is a pinion on lever o, Thus it will'be observed that the operator has entire and c omplete control over the machine'bynieansoi' the hand-lever h. ppm-e slotted pieces provided with ears. Through these ears the. shnftd extends and derives its bearings from them. -Behind these slotted pieces are the slidesc 0; These slides rest against the seed-slide D, andare governed by the th nmb-s crewsjj. V

The operfition of our machine is so obvious that it requires no description to enable one with ordinary intelligence to work it.

I What we claim, and desire to secure-by Letters Patent, is i a 1. The shaking-bar b, when provided with pins e e and stirrers z' is, in combination with cam-wheels B B,-f 1 as and for the purpose set forth. 7 i

. 2. Theslide D, provided with rack g, in combination with shaft 0? and pinion a, substantially in the manner and for the purpose specified. I V r l l 3. We claim the peculiar gear-arrangement, in combination with shaft m, provided with brushes, shaft d, pinion a, and slide D, substantially in the manner and for the purposes described. l i

In testimony that we-elaim the above, we sign our ndmes in presence of two witnesses.
